Anti-Stall (Standard)
The Anti-Stall feature prevents the engine from
stalling by reducing the hydraulic output for the
lift, tilt, and auxiliary functions. When engine
speed is between 850 and 600 rpm, the spool activa-
tion signal is proportionally reduced every 2 sec-
onds. When engine speed is recovering, the reduced
spool activation will increase every 4 seconds until
the spools are fully activated according to the posi-
tion of the lever.
In the event engine speed is below 600 rpm, the
output signal for lift, tilt, and auxiliary functions is
set to zero to completely remove the hydraulic load
immediately.
Temperature Protection (Standard)
The Temperature Protection feature warns the op-
erator of extreme hydraulic oil temperatures by dis-
playing the fault code h-cold or h-hot. When h-hot
is displayed, a warning light turns ON simultane-
ously.
Low Temperature Protection (Standard)
Depending on the hydraulic oil temperature, engine
speed is reduced proportionally in order to protect
the hydraulic pumps against cavitation. See Ta-
ble 1 for the relationship between temperature and
maximum engine speed. When the Low Tempera-
ture Protection is activated, the fault code h-cold is
displayed.

High Temperature Protection (Optional)
The High Temperature Protection feature limits ve-
hicle speed to 10 km/h (6 mph) when hydraulic oil
temperature is above 90°C (194°F) to reduce the
heat generated during braking. When High Tem-
perature Protection is activated, the fault code h-
hot is displayed.
Dynamic Control (Optional)
The Dynamic Control feature consists of two differ-
ent components:
• Dynamic Load Compensation uses informa-
tion from the pressure sensor to adjust the
lowering output signal.
• Dynamic Ramp Times scales actual ramp
times between a maximum increase/decrease
time when the truck is fully loaded, and a
minimum increase/decrease time when the
truck is empty. Depending on the actual
load, ramp times will vary between rapid,
normal, and smooth.
Loaded Speed Reduction (Optional)
The Loaded Speed Reduction feature limits vehicle
speed when the weight of the load exceeds a certain
value. The required input signal is provided by the
pressure sensor. The Hydraulic User Interface Pro-
gram allows adjustment of both weight and limited
vehicle speed.
NOTE:
Loaded Speed Reduction is different from
container handler speed limitations that can be
triggered either by exceeding a certain lift height
for a container, or by insufficient locking of a con-
tainer for model 584.
